Age you wish to retire. This calculator assumes that the year you retire, you do not make any contributions to your retirement savings. So if you retire at age 65, your last contribution happened when you were actually age 64. This calculator also assumes that you make your entire contribution at the end of each year.

Household income

Your total household income. If you are married, this should include your spouse's income.

Current retirement savings

Total amount that you currently have saved toward your retirement. Include all sources of retirement savings such as 401(k)s, IRAs and Annuities.

Rate of return before retirement

This is the annual rate of return you expect from your investments before taxes. The actual rate of return is largely dependant on the type of investments you select. From January 1970 to December 2004, the average compounded rate of return for the S&P 500, including reinvestment of dividends, was approximately 11.5% per year. During this period, the highest 12-month return was 64%, and the lowest was -39%. Savings accounts at a bank pay as little as 1% or less. It is important to remember that future rates of return can't be predicted with certainty and that investments that pay higher rates of return are subject to higher risk and volatility. The actual rate of return on investments can vary widely over time, especially for long-term investments. This includes the potential loss of principal on your investment.

Rate of return during retirement

This is the annual rate of return you expect from your investments during retirement. It is often lower than the return earned before retirement due to more conservative investment choices to help insure a steady flow of income. The actual rate of return is largely dependant on the type of investments you select. From January 1970 to December 2004, the average compounded rate of return for the S&P 500, including reinvestment of dividends, was approximately 11.5% per year. During this period, the highest 12-month return was 64%, and the lowest was -39%. Savings accounts at a bank pay as little as 1% or less.
